Abstract

A theoretical investigation is made to study the properties of dust magnetosonic (DMS) solitons in a magnetized electron–ion–dust plasma that contains negative polarity warm dust grains, and inertialess ions as well as electrons. By using reductive perturbation technique (RPT), the Korteweg–de Vries (KdV) equation is derived. There is the formation of only positive potential DMS solitons in the high plasma-β limit. The effects of plasma parameters, viz., plasma-β, electron to ion temperature ratio and dust to electron density ratio on the characteristics of DMS solitons are also studied numerically. Furthermore, we have analysed the head-on collision of DMS solitary waves and subsequent evolution of stationary structures using INSAT FORK code. Results of this investigation might be useful for understanding the nonlinear disturbances in space plasmas especially in Earth's magnetosphere region and are also useful in understanding the energy transport phenomena of nonlinear structures.
